IMPROVEMENT IN GRAlN-SEPARATORS.

Specification forming part of Letters Patent N 0. 215,078, dated May 6, 1879; application filed December 7, 1878. I

To all whom it may concern.-

Be it known that 1, JOHN H. STURGEoN, of Owensville, Gibson county, Indiana, have invented Improvements in Grain-Separators, of which the following is a specification.

My invention is an improved grain-separa tor, constructed as fully described hereinafter, so as to increase its efiiciency, simplify its construction, and permit it to be easily regulated- In the drawings forming part of this Speci; fication, Figure 1 is an elevation of a separator with my improvements; Fig. 2, a perspec tive View of the frame; Fig. 3, an end view; Fig. 4, a transverse section.

The machine consists of the supportingframe A, case B, and reel 0. The frame consists of a pair of end pieces, a a, connected by bars I), the legs a having extensions or lugs c, with parallel faces to receive and hold the case, as shown.

The case is divided horizontally in the center into sections 61 cl, the upper being rounded, and the lower having inclined sides 6 e and a flat bottom, 6.

The case rests between the cross-legs of the end pieces, as shown in Figs. 1 and 3, the forward end bearing upon the rounded projection 'i of a lever, D, pivoted to the end piece, a, and

having at the other end a perforated strap, f,

hanging from a pin, g.

The reel consists of parallel bars supported by arms-m, radiating from the central shaft, 8, and carryin g sections of cookie-wire, graduated to divide the grain into different grades, the grain being fed from a hopper, H, at one end.

Through the bottom c extend three chutes, and within the lower section are plates w, inclined from each side toward each chute,and, with the inclined sides forming funnels for directing the different grades of grain to their respective chutes, beneath which, upon hooks u, are directly suspended the bags.

At the outer end of the case is an opening, .9, closed by a door, 19, and so arranged that a tool may be introduced either above or below the cockle-wire, to clean the latter, &c.

In grading the material, the inclination of the machine'is a matter of much importance. For instance, if there is but a small portion of fine material and the inclination is too great, the fine material will not be sifted out, but Will pass forward. If the inclination is not suflicient, the operations will be delayed.

By adjusting the lever D the inclination of the case and reel may be altered as required duringthe passage of the grain, this adjustment being quickly effected by means of the strapf and pin g, the rounded projection z insuring a bearin g on the bottom near the cen ter whatever may be the adjustment.

' The case, being detachable from theframe A, may be readily removed and cleaned, while the whole structure-is so simple that the machine may be readily made at a slight expense.

I claim 1. The casing B, containing the reel 0, and provided with an opening, 8, arranged to permit access above and below thecockle-wire of the reel, as specified.

2. The combination of the end pieces, a a, the latter having parallel guiding projections c c, the strips I) b, lever D, pivoted to the end piece, a, and having a rounded projection, z, arranged to afi'ord a rest for the flat bottom of the case B, and the adjusting-strap and pin f g, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN H. STURGEON.
